3

Day 4: Revise & Test

Revise key formulas and concepts without looking at notes. Take a practice quiz to test your understanding.

What to Focus On

  • Elasticity is the ability to regain original shape and size after removing deforming force
  • Elastic substances return completely to original form; plastic substances retain permanent deformation
  • Spring-ball model explains atomic basis of elasticity

  • Stress = Force/Area, measured in N m⁻² or Pascal
  • Strain = Relative change in dimension, dimensionless
  • Tensile stress stretches, compressive stress compresses

  • Stress is directly proportional to strain for small deformations
  • The proportionality constant is called modulus of elasticity
  • Valid only within elastic limit of the material

Common Mistakes to Avoid

Stress equals force and strain equals extension - they are the same as F and ΔL

Higher Young's modulus means the material is weaker and less elastic

Poisson's ratio can have any positive value between 0 and 1
